Nurses are expected to act within and ethos of care cognisant of duty, the right and the good. Concepts of virtue theory, utlitarianism and deontology are used to outline a conceptual ethical framework for nurses in practice. This 'Moebius' framework aims to locate the virtues in a symbiotic relationship with the principles of utilitarianism and deontology. Under this framework, fitting ethical responses are sought. Within an ethic of the fitting, rules and principles do not guarantee the most ethically justifiable outcomes. Within the Moebius approach, the nurse ought to respond with a sense of compassion that befits the moment rather than adhere to a rule at all costs.
